A lack of understanding about mental health problems is creating a stigma with some employers, according to a psychologist.

Nick Adams explained that many jobseekers will not disclose the fact they have suffered from mental health problems or depression in the past, as they feel it does not impact on their work but may be detrimental to their job chances.

'The truth is that many people in employment may have mental health problems that their employers are unaware of. Some people can channel their thoughts in work and even become more productive as work gives them good feelings,' Mr Adams said.

However, he added that unfortunately there is still a stigma attached to mental health issues, so jobseekers who tell recruiters they have suffered from the problem may be at a disadvantage.

Emma Mamo, policy and campaigns manager at Mind, said that long term unemployment can cause depression in some cases, especially among men who closely associate working with their personal identity.
